10.1 Calculate the nominal strength Pn for the section of the figure for Problem 10.1 for an eccentricity ey (measured along the y-axis) = 0.1h = 1.8 in. Use f'c = 3000 psi and fy = 40,000 psi. Use basic principles of statics to obtain solution, considering the effect of compression concrete displaced by steel; compare the result with the maximum Pn given by ACI-22.4.2 (e = 46 mm; f'c = 20 MPa; fy = 300 MPa).
